ORE-CRUSHER.

SPECIFICATION forming part of Letters Patent NO. (397,802, dated April 15, 1902.

Application filed March 12. 1900. Serial No. 8,374.. (No model.) I

To all whom it may concern.-

Be it known that I, ALBERT CHAMPLIN CALKINs, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Crusher for Ores and other Materials, of which the following is a specification.

An object of my invention is to provide a crusher adapted to crush coarse frangible material to produce a product of more uniform fineness than has heretofore been obtained by other types of crushers.

Another object of my invention is to increase the life of the machine with a minimum expenditure for replacing worn parts.

Another object is to provide for readily cleaning the interior of the machine of all material. Provision is made for readily cleaning the whole interior by removing the mechanism and a part of the frame at the front end of the machine. This is especially desirable in laboratory work of assayers and chemists, inasmuch as it obviates the liability of salting specimen samples by contamination with any former crushings which may have remained in the machine.

Another object is to afford more ready and accurate adjustment of the size of the discharge-opening of the machine, thus to regulate the maximum size of the product crushed.

The accompanying drawings illustrate my invention.

Figure I is a perspective View of the machine ready for operation. Fig. II is a fragmental diagram, in side elevation. of the rotary and vibratory sections. Fig. III is a vertical mid-section of the machine on line III III, Fig. IV. Fig. IV is a plan, partly in section, on line IV IV, Fig. III. Fig. V is an enlarged detail, in axial section, of the rotary member of the fixed jaw on line V V, Figs. III and IV.

a indicates the non-vibrating jaw, composed of an upper plain fixed section 1, where the heavy crushing takes place, and the lower rotary section 2, which is in the form of a heavy smooth faced cylindrical roll and which rotates downwardly inwardly toward the vibratory jaw b, which is composed of a heavy body 3, provided with a heel extension 4 and with a reversible replaceable wearingfaoe 5. The heel portion 4 is seated in a socket 6, held by themain frame 7 of the machine. The body 3 0f the vibratory jaw is op erated by a connecting-rod 8, driven by the eccentric shaft 9 in the ordinary way. The upper end of the body of the vibratory jaw vibrates in an approximately horizontal arc.

10 indicates a reversible replaceable Wearing face-plate, which forms the wearing-face of the fixed part 1 of the non-vibrating jaw a. The wearing-face at the lower edge of the replaceable face-plate 5 of the vibratory jaw is formed in the segment of the outer face of a cylinder, as at 0, described from the axis 01 of rotation of the heel 4, and extends through the arc of vibration contiguous to the roll portion of the non-vibrating jaw, the said segment being of such an extent relative to the amplitude of vibration of the Vibratory jaw that the nearest tangential points of the two jaws will always be equidistant. The wearing-face at the upper edge of the wearing faceplate 5 is curved to the same radius, so that the face-plate 5 is reversible.

The upper fixed section 1 of the non-vibrating jaw a is composed of a block 11, with the face-plate 10 secured thereto by a screw 12. The block 11 is provided with lateral exten- 8o sions 13 to fit in gains 14 in the frame.

15 indicates eyes or staples projecting forward from the block 11 to receive a wedge 16, which wedges against the out-er external face of the frame and holds the block firmly at any desired height in relation to the lower rotary section 2 of the non-vibrating jaw. By driving the wedge 16 into place after the block has been dropped into the frame the block is positively secured in place and prevented from slipping downward or becoming loose. The gains 14 extend down in the frame of the machine to a greater depth than the ordinary adjustment of the jaw will require,

.so that the jaw may be adjusted as to height 5 and held in place by the wedge 16. The block can be readily removed by driving out the wedge, and the face-plate can be taken off and turned with upper edge downward, to thus restore this section of the jaw to perfect zco working condition after the lower edge has been worn away.

,ried by two frame members 22, which are pivoted to the frame by pivots 23 at the lower end and are fastened to the frame at the up per end by loose pins 24. WVhen in working position, the frame members 22 constitute rigid portions of the frame, and by adjusting the screws and 21 the blocks 18 may be adjusted toward or from the vibratory jaw to decrease or increase the size of the dischargeopening. When the rotary member 2 is thus brought nearer to or farther from the vibratory jaw, the relations of the fixed and rotary portions of the non-vibrating jaw may be maintained by driving out the wedge 16 and raising or lowering the block 11, .as the case may require, and then retightening the wedge to hold the block in the desired position. The roll 2 is preferably provided with a phosphorbronze bushing 25, which is driven tightly into the roll 2, so as to rotate therewith on the shaft 17, which is fixed to the blocks 18 by means of a set-screw 26. The phosphorbronze bushing 25 is somewhat longer than the roll 2 and is housed in the blocks 18, thus to prevent any dust from penetrating to the wearing-face of the shaft. The blocks 18 are provided with shoulders e to engage the inside of the slidewayslt) of the frame in which the blocks are adj ustably mounted to prevent thrust.

27 indicates an oil-inlet leading from one end of the shaft into the interior of the roll to lubricate between the roll and the shaft 17.

28 indicates a scraper, which is formed of a plate 9, bent around and thereby pivoted on a shaft it, carried by the frame 7.

'i indicates a slot in the plate, through which extends a counterweight rod or barj, which holds the plate g in engagement with the roll 2. y

In order to provide a larger supportingface for the screws 21 to engage the blocks 18, which carry the shaft, the screws are each provided on their inner ends with an enlarged head 70, andthe screws are inserted outward from the inner portion of the frame members 22. 'lheouter end of each of the screws 21 is provided with an angular reduced portion m, to be turned by a Wrench.

In the drawings,nindicates a spring-actuated draw-rod for holding the vibratory jaw 12 firmly against the socketfi and the connecting-rod 8 to take up any lost motion and to prevent any looseness of the parts. This is a common expedient and is not claimed as a part of my invention.

0 indicates a clamp for serving the double purpose of a box for the connecting-rod and a retainer for the face-plate 5 of the vibratory The clamp 0 is provided at its rear with a downwardly-projecting,fingerp, which passes through a slot q in the connecting-rod- 8 to hold the end of the connecting-rod in the socket 8. The front. edge of-the clamp 0 is provided with a downwardly-extending lip r to fit onto the upper edge of the wearing faceplate 5, and the body 3 of the vibratory jaw b is provided with a corresponding lip s at its lower extremity to seat the lower edge of the face-plate 5.

tindicates alag-screw which passes through the clamp 0 and screws into the upper end of the body 3 of the vibratoryjaw to hold the clamp in place.

a, Fig. III, indicates a friction-dog pivoted to a block n, which slides in a gain w in one of the frame members 22.

00 indicates an adjusting-screw for holding the dog in proper relation to the roll-section 2 of the stationary jaw. This prevents'the roll from rotating backward.

y indicates a crank, and z 2' indicate the fly-wheels of the machine. The crank y is detachable, and the fly-wheel z is arranged to be used as a pulley, so that the machine may be driven by power, if desired.

In practical operation motion is imparted to the vibratory jaw by rotating the fly-wheels as, and the material is fed between the jaws in the ordinary manner. The material on en tering the machine is first cracked between the upper crushing-surfaces and falls down between the roll 2 and the lower portion of the vibratory jaw and is further crushed, and when reduced to a fineness sufficient to pass through the aperture between the segmental portion 0 of the vibratory jaw and the segment of the roll contiguous thereto the material will fall through into thev chamber 30 of the frame. The maximum size of the product may be readily adjusted by adjusting the screws 20 and 21. The adjustingscrew 68 of the dog will also be tu rned to maintain proper relation of the dog .when under new adjustment. Under the vibratory action the friction of the material being crushed will cause a rotation of the roll 2, thus permitting and forcing the discharge, but maintaining a uniform size of outlet-opening and constantly offering a new wearing-surface in opposition to the vibratory jaw. The edge of the scraper 28 is held by the weight of bar j against the rotating roll, thus removing from the surface of the roll any material which adheres thereto. When the desired charge has been crushed, the machine is readily opened for perfect cleaning by withdrawing the pins 24 and the wedge 16, so that the roll 2 and the block 11 may be entirely removed from the frame,thus

allowing perfect access to all of the parts to which any of the material might adhere.

82 indicates steel wear-plates at the opposite faces of the open space, which extends from front to rear at the top of the frame and in which space the non-vibrating and vi bratory jaws are mounted.
